This document provides an overview of deploying and configuring DNS service. It discusses the DNS architecture based on IP addresses and name resolution. The objectives of DNS are to assign host names without duplication, store the host name database across multiple servers to avoid bottlenecks, and create a standardized naming system. DNS has three main elements - the DNS name space organized in a tree structure with domains and resource records, name servers that contain information about domains and resource records, and resolvers which are client programs that generate queries to the name servers. The document explains how the DNS process works with queries being resolved through a series of DNS servers.
A Domain Name System assigns an alphabetic name to a numeric IP address and is made up of multiple Domain Name servers that enable IP address mapping for devices on the Internet (usually servers).
This Presentation explains about Domain Name System Records and Their Usage.

The DNS name space is based on a domains, which exist in a hierarchical structure much like the directory tree in a file system.
A domain is the equivalent of a directory, in that it can contain either subdomains (subdirectories) or hosts (files), forming a structure called DNS tree.
The DNS name space function in the same way : administrators are assigned domain names and are then responsible for specifying host names to systems within that domain.
The result is that every computer on the Internet is uniquely identifiable by a DNS, name that consists of host name plus the names of all its parent domains, stretching up to the root of the DNS tree, separated by periods.
Each of the names between the periods can be up to 63 characters long, with a total length of 255 characters for a complete DNS name.
Domain and host names are not case sensitive, and can take any value except the null value.
Learn about the essentials of the Domain Name System (DNS), including name resolution, different record types, roots, zones, authority and recursion.

Domain Name System (DNS) - Domain Registration and Website Hosting BasicsAsif Shahzad
I teach Web Technologies course at COMSATS University to undergrad students. These are lectures slides prepared for students. I thought to share it with all. Hope you would like it. It contains good enough details about how DNS, Hosting and Domain Registration works.
The Domain Name System (DNS) is a hierarchical decentralized naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates more readily memorized domain names to the numerical IP addresses needed for the purpose of locating and identifying computer services and devices with the underlying network protocols. By providing a worldwide, distributed directory service, the Domain Name System is an essential component of the functionality of the Internet.
Overview of the Domain Name System (DNS).
In the early days of the Internet, hosts had a fixed IP address.
Reaching a host required to know its numeric IP address.
With the growing number of hosts this scheme became quickly awkward and difficult to use.
DNS was introduced to give hosts human readable names that would be translated into a numeric IP addresses on the fly when a requesting host tried to reach another host.
To facilitate a distributed administration of the domain names, a hierarchic scheme was introduced where responsibility to manage domain names is delegated to organizations which can further delegate management of sub-domains.
Due to its importance in the operation of the Internet, domain name servers are usually operated redundantly. The databases of both servers are periodically synchronized.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Deploying and configuring dns service
1. Deploying and
Configuring DNS Service
70-410 EXAM OBJECTIVE: DEPLOY AND CONFIGURE DNS
SERVICE. THIS OBJECTIVE MAY INCLUDE BUT IS NOT LIMITED TO:
CONFIGURE ACTIVE DIRECTORY INTEGRATION OF PRIMARY
ZONES; CONFIGURE FORWARDERS; CONFIGURE ROOT HINTS;
MANAGE DNS CACHE; CREATE A AND PTR RESOURCE RECORDS.
2. The DNS Architecture
Based on IP addresses
Each computer has at least one network interface
(host)
Each host has unique IP address.
Every datagram sent by TCP/IP has the senders and
recipients IP Address.
Friendly names must be converted to IP Addresses
Early days- Host Table
Today- DNS Servers provide Name Resolution
3. Objectives of DNS
Assign host names to computer without
duplication.
Store host names in database accessible by
any system on network.
Distribute host name database among servers
on network to avoid traffic bottlenecks.
Create standardized system for naming hosts.
4. Three elements of DNS
DNS Name Space
Tree structured name space.
Each branch identifies a domain.
Each domain contains resource records
Host names
IP Addresses
Other Information
Queries retrieve specific resource records
from domain.
5. Three elements of DNS
Name Servers
DNS Server-Application that contains
information about the domain tree structure
and usually one or more specific domains in t
that structure.
6. Three elements of DNS
Resolvers
Client program that generates DNS queries and
sends them to DNS server for fulfillment.
7. How the process works
A computer on the network sends a request to its
assigned DNS server
If that server does not have the information, it forwards
the request to the DNS server that has that information.
That DNS server replies to the first server with the IP
address requested
The first DNS server then replies to the user who
originated the request, giving them the requested IP
address.
